     6  * This test uses a formhistory.sqlite with schema version set to 999 (a

     7  * future version). This exercies the code that allows using a future schema

     8  * version as long as the expected columns are present.

     9  *

    10  * Part A tests this when the columns do match, so the DB is used.

    11  * Part B tests this when the columns do *not* match, so the DB is reset.
